Participants who agree to be involved in the focus groups will be recruited via existing community contacts (e.g., Aboriginal elders, leaders of community groups and doctors who support the planned research) in urban Adelaide and regional Murray Bridge. We also intend on actively recruiting through clinic visits made by our visiting respiratory clinicians. Copies of the participant information sheet and consent form will be disseminated via local healthcare workers to seek focus group volunteers and via existing contacts in health and by word of mouth for one-on-one interview participants. Survey participants will be recruited as per above methods in addition to use of delegate lists and mail outs.
